so i beat the final boss and was going to try and play new game plus but it like fucked deleted my save and forgot i ever beat the game???? im stuck back at the start (beat dhar and went to the first mosnter after which is when i was told that it would tell me i got my stuff back) and i have no abilites or anything. im not playing through this game again with nothing. does anyone have any sort of fix for this or am i just fucked? im on console (xbox series x) if that matters. this has just totally killed my interest in continuing to play the game so thats great if its just lost forever.
